Could AI discover a new law of physics?

Yes—AI could plausibly help discover a new law of physics, especially by analyzing large datasets to find hidden patterns, relationships, or compact mathematical descriptions that people might miss. There are already examples of AI rediscovering known physical laws and proposing useful alternative descriptions of systems.

That said, finding a candidate law is not the same as establishing a new fundamental law of nature. Any AI-generated result would still need to be interpreted, tested, and validated by physicists, ideally across independent data and experiments. So the best answer is: yes, AI may help discover new physics, but human scientific verification is still essential.
